Anti-wrinkling structure of sewing machine

Abstract

The invention relates to an anti-wrinkling structure of a sewing machine. The anti-wrinkling structure comprises a frame, and a bedplate and a driving device which are arranged on the frame, wherein a headpiece is arranged on the bedplate; a machine needle is arranged on the headpiece; a needle plate is arranged below the machine needle; conveying devices are arranged on two sides of the needle plate on the bedplate; and tip-shaped bulges are arranged on the conveying devices. The anti-wrinkling structure is simple in structure; when a cloth material is placed on conveyor belts, the tip-shaped bulges on the conveyor belts are buckled into small holes of the cloth material, the friction force is increased, the cloth material is pulled by a pull force, so that the cloth material is prevented from deforming and wrinkling during sewing, the sewing quality is good, the cloth material is attractive in appearance, and simultaneously the conveyor belts can drive the cloth material to move forwards and the cloth material is not pulled; and the anti-wrinkling structure has great application and promotion values.

Description

technical field [0001] The invention relates to a sewing machine component, in particular to a wrinkle-proof structure of the sewing machine. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. The sewing machine can sew fabrics such as cotton, fiber crops, silk, wool, artificial fibers and products such as leather and plastics. Existing sewing machines generally include a platen and a foot pedal installed on the frame, a machine head and a needle plate are installed on the platen, the machine head is provided with machine needles, and the cloth can be sewed on the needle plate. When sewing, the cloth cannot be made to be tight, so that the top thread or bottom thread that is sewn out is sometimes tight and sometimes loose, and the stitches are very ugly, which has a strong impact on the quality of sewing.
